Dr. Jonathan Crane isn't crazy, he just likes to put on a scarecrow mask and terrorize Gotham City with his own form of weaponized fear gas. You can be just like him if you like. All you need to do is put on this mask, hang around Arkham Asylum, maybe team up with Ra's al Ghul and mess with Batman. We can get you all set up with the mask, but we lost Ra's al Ghul's number, so you might have to check the phone book for that.
